I’m not just throwing that word around. It’s based on the same GK104 GPU at the heart of Nvidia’s current-generation single-GPU leader, the GTX 680, and its performance stops just shy of what you’d get with two of those hooked up in SLI; Nvidia’s claims of this being the fastest video card in the world weren’t exaggerations.
